Its change in y / change in x so the y value changes by -4-7 so -11 and the x value changes by -3-5 so -8 so the gradient is -11/8

Answer:


(11)/(8)

Explanation:

Slope formula


\textsf{Slope}=(y_2-y_1)/(x_2-x_1)


\textsf{where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.}

Define the points:


\textsf{Let}\:(x_1,y_1)=(5,7)


\textsf{Let}\:(x_2,y_2)=(-3,-4)

Substitute the defined points into the formula:


\implies \textsf{Slope}=(-4-7)/(-3-5)=(-11)/(-8)=(11)/(8)

Therefore, the slope of (5, 7) and (-3, -4) is 11/8.
